US senator blasts president of Mexico, says toxic sewage dump threatens ‘national security’

More than '100 billion gallons' of poisonous toxic waste have poured into Southern California, prompting Senator Tim Sheehy, R-Montana, to write a letter to Mexican president Claudia Sheinbaum.

"This continuous discharge is sickening thousands of Americans annually, including U.S. Navy SEALs and Marine special forces who train in the affected waters," the letter to the president of Mexico reads. "In February 2025, the Department of Defense Office of Inspector General concluded that, absent action, Navy Special Warfare Command would be advised to cancel or relocate up to 75 percent of water training exercises at Naval Amphibious Base Coronado due to elevated bacterial contamination levels."

Last week, the International Boundary and Water Commission stated that Mexico is dumping 5 million gallons of sewage a day into the Tijuana rRver. The toxic waste then flows up into the United States, and can even make its way into the Pacific Ocean.
